Retirement tax questions

Thank you for the reply.  I did file as Married filing Jointly for 2018.   My concern was for this year 2019.  Now that I just got these 1099-C's.   What if anything do I have to do.  File a tax return for her under her estate, which there wasn't one.  She had no income at the time of death, no property of her own, no savings.  I was just worried that living in a commuity property state I would have to declare the debit as my income even though it's been a year since her death.  Or for that matter if another 1099-C shows up in any upcoming years.
